More specifically, embodiments of the present technology include systems and methods for implementing machine learning models within industrial control code to improve performance, increase productivity, and add capability to existing control programs. In an embodiment, a system comprises an interface component configured to display a graphical representation of a machine learning asset in an industrial automation environment, wherein the graphical representation includes a visual indicator representative of an output from the machine learning asset.

BACKGROUND

Industrial manufacturing environments generate huge quantities of data at very fast speeds making the extraction of enterprise-level insights challenging. In industrial automation environments, control systems are used to drive various operations along an industrial line. Control code is used by industrial drives or programmable logic controllers to drive industrial assets, devices, and sensors in an industrial process. Operational data produced during runtime contains important information about the status, performance, or quality of the industrial process, but can be difficult to leverage in real time given the enormous amount of computing power and time that goes into operational analytics. Moreover, control programs are typically developed by programmers prior to implementation and the ability to adjust control programs after implementation or during runtime is limited. Manually editing control programs in response to various information in operational data can be an extremely difficult and time-consuming process that requires intimate knowledge of data science and process control. Automating the editing of control program can be even more difficult.

Machine learning algorithms are designed to recognize patterns and automatically improve through training and the use of data. Examples of machine learning algorithms include artificial neural networks, nearest neighbor methods, gradient-boosted trees, ensemble random forests, support vector machines, naïve Bayes methods, and linear regressions. A machine learning algorithm comprises an input layer and an output layer, wherein complex analyzation takes places between the two layers. Various training methods are used to train machine learning algorithms wherein an algorithm is continually updated and optimized until a satisfactory model is achieved. One advantage of machine learning algorithms is their ability to learn by example, rather than needing to be manually programmed to perform a task, especially when the tasks would require a near-impossible amount of programming to perform the operations in which they are used.

It is with respect to this general technical environment that aspects of the present disclosure have been contemplated. Furthermore, although a general environment is discussed, it should be understood that the described examples should not be limited to the general environment identified in the background.

Those skilled in the art will appreciate that the features described below can be combined in various ways to form multiple variations of the invention. As a result, the invention is not limited to the specific examples described below, but only by the claims and their equivalents.

Various embodiments of the present technology generally relate to solutions for integrating machine learning models into industrial automation environments. More specifically, embodiments of the present technology include systems and methods for implementing machine learning models within industrial control code to improve performance, increase productivity, and add functionality to existing control programs. Generally, industrial control code provides instructions for controlling and performing certain operations within an industrial environment via controllers (e.g., programmable logic controllers or “PLCs”), wherein the controllers execute the control code to control downstream devices and machinery.

The present technology serves to greatly enhance industrial control by enabling the use of machine learning models within control code for more advanced control. Many programmers responsible for generating control code, however, lack the expertise, resources, or time to write and train their own machine learning models for use within their target environment. Thus, in an implementation of the present technology, machine learning models may be pre-packaged and provided to programmers in the industrial control programming environment just as another industrial asset may be. For example, a control code programming environment may traditionally allow a programmer to “drag and drop” known industrial assets into the process being programmed, wherein the selected asset may come with pre-set parameters and/or settings. The programmer can then connect the asset to other assets, devices, models, inputs, or outputs when building the process. In a similar way, a programmer, in accordance with the present disclosure, may “drag and drop” a machine learning model into the process being programmed, wherein the selected model may similarly come with pre-set parameters, training, and/or settings. The programmer can then connect the model to other assets, devices, models, inputs, or outputs when building the industrial process, as well as apply logic to its input or output. In many examples herein, the model is integrated in a closed loop environment—given that much industrial processes are closed-loop processes—wherein the output of the model is factored into the control logic itself. However, a machine learning model in accordance with the present disclosure may be in communication with external networks providing additional data.

Thus, the provided models are capable of being added into a program using the same input/output (I/O) capabilities as other industrial assets or objects. In accordance with the present disclosure, data scientists may develop and release new machine learning models, which then become available as objects in a programming menu in the same manner as any other device or asset—such as controller and sensors. A programmer may, in an example, be able to add a provided model to a control line via the control program as well as set up inputs and outputs to and from the model. Preferably, the model's outputs adhere to the same paradigm as any other available device such that they can be tagged and usefully integrated into the program.

In an embodiment, a model may consume data relevant to live operations within an industrial automation environment and provide an output that assists the control program in controlling assets based on the consumed data. For example, an input to the machine learning model may be data from a temperature sensor monitoring ambient air temperature within a milk cooling process. In response to input from the temperature sensor, the model may determine that, due to variability on the temperature sensor, the line (i.e., the cooling process) should be slowed down a certain amount to improve output quality. Thus, output from the model may direct an industrial drive to properly slow down the process to achieve a higher quality output.

In an alternative example, a model implemented in a beverage production line receives input from an economic survey on beverage consumption. Based at least in part on the beverage consumption information, the model provides an output that is used as a parameter in the control logic being executed on the line. Thus, when the model predicts a slowdown in beverage consumption, it's prediction can be factored into control logic to slow down the line.

In accordance with the present disclosure, a machine learning model comprises one or more machine learning algorithms that are trained based on historical data and/or training data. A machine learning model may employ one or more machine learning algorithms through which data can be analyzed to identify patterns, make decisions, make predictions, or similarly produce output that can inform control code and/or parameters. Examples of machine learning algorithms that may be employed solely or in conjunction with one another include artificial neural networks, nearest neighbor methods, ensemble random forests, support vector machines, naïve Bayes methods, linear regressions, or similar machine learning techniques or combinations thereof capable of predicting output based on input data. Determining which machine learning methods to use may depend on the specific purpose or functions required in a particular industrial setting. A machine learning asset, in some examples, outputs a decision regarding a mode in which the industrial process should be run, wherein that output can be used to adjust parameters and/or settings for controlling the process. In other examples the machine learning asset outputs the determined parameters and/or settings directly for integration into the control code. Other outputs with a similar purpose may exist and are contemplated herein.

Machine learning models may be implemented to perform asset and/or optimization in industrial automation environments. That is, models are used to edit control code such that a device or process is optimized according to a specific control scheme. For example, models can be trained and used to optimize performance, yield, energy consumption, cost, or similar.

Moreover, machine learning models may be implemented to assist in model lifecycle management. A model inherently has a useful lifecycle as the environment around it changes. Over time, models become ubiquitous and can, in essence, wear out, just like any other machine or sensor on an industrial line. Thus, machine learning is utilized to track and/or recognize error between predictive and actual outcomes for purposes of process performance management and/or autonomous manufacturing. In accordance with the present disclosure, machine learning is used for lifecycle management of models that are focused on the closed-loop control of assets in production lines and manufacturing—an may be used in autonomous manufacturing environments.

To accompany the use of control program integrated models, corresponding faceplates are contemplated herein to provide intuitive representations and interfaces to models on-site. A machine learning model faceplate may comprise basic controls and/or visuals relevant to the model that can be utilized and accessed within the control environment. In this manner, provided machine learning can be brought into the on-site user experience more fully as well as into the programming environment. For example, an operator can view or use a model faceplate on a kiosk within the industrial automation environment to perform a task such as turning the model on or off, disconnecting the model from the line, or monitoring the model. The faceplate, in just a few examples, may also be useful for performing slightly more complex tasks such as offsetting parameters, providing inputs, tuning parameters of the model, overriding the model, or checking the status of the model.

FIG. 2A illustrates an example of a typical PLC-driven loop for controlling an industrial automation process. FIG. 2A includes PLC 201, HMI 202, actuators 203, controlled process 204, and sensors 205. PLC 201 provides output that drives actuators 203. Actuators 203 actuate controlled process 204. Sensors 205 capture output data from controlled process 204 and provide that data back to PLC 201 to complete the loop. PLC 201 is coupled to HMI 202, which may present data for operator viewing or enable operator action affecting the process (e.g., adjusting parameters). FIG. 2A provides an example of a system that runs an industrial process prior to implementation of the disclosed technology. FIGS. 2B-2D illustrate the beneficial inclusion of machine learning models in such industrial processes.

FIG. 2B illustrates an example of one way in which a machine learning model may be integrated into a PLC-driven loop for controlling an industrial automation process. The loop of FIG. 2B comprises machine learning asset 211, input/output (I/O) 212, HMI 213, PLC 214, HMI 215, actuators 216, controlled process 217, and sensors 218.

As previously discussed, machine learning asset 211 may comprise one or more machine learning algorithms trained to produce output usable by PLC 214 based on input from I/O 212 and/or input from sensors 218. Machine learning asset 211 is coupled with HMI 213, wherein HMI 213 may include a display that provides a graphical representation of the machine learning asset in industrial automation environment. The graphical representation may include one or more visual indicators relevant to the machine learning asset, such as visual indicators of input, output, status, or other metrics. In some examples, the HMI comprises a faceplate for viewing or use by an operator or similar user within the field environment.

In the present example, PLC 214 receives an output from machine learning asset 211. In some embodiments, the output from machine learning asset 211 is the direct output or prediction from the machine learning model. PLC 214 controls controlled process 217 by directing actuators 216 based on process code. Actuators 216 actuate controlled process 217. Sensors 218 collect data from controlled process 217 and provide some or all of the collected data back to machine learning asset 211. Sensors 218 may provide collected data to additional assets as well, such as PLC 214 or external assets not shown in FIG. 2B.

FIG. 2C illustrates an additional example of one way in which a machine learning model may be integrated into a PLC-driven loop for controlling an industrial automation process. The loop of FIG. 2C comprises external network 221, machine learning asset 222, PLC 223, HMI 224, actuators 225, controlled process 226, and sensors 227. In some examples, the loop of FIG. 2C further comprises an additional HMI coupled to machine learning asset 222. In the example of FIG. 2C, machine learning asset 222 is in communication with external network 221, which may comprise a local area network, a wide area network, a cloud network, the Internet, or similar Machine learning asset 222 receives or collects data from external network 221 and uses that data as input to the one or more machine learning algorithms within machine learning asset 222. Machine learning asset 222 then provides its output to PLC 223 in the form of a prediction, a determination, control parameters, or the like. PLC 223 then controls controlled process 226 based at least in part on the output from machine learning asset 222 via actuators 225. Sensors 227 collect data from controlled process 226 and provide that data to PLC 223 and to additional places in some examples. In an embodiment, data collected by sensors 227 is also provided to machine learning asset 222 and used as input.

FIG. 2D illustrates an example of an HMI for a machine learning asset in an industrial automation environment. HMI 231 is representative of any computing device capable of acting as an interface between industrial data relevant to a machine learning asset and a user in the industrial environment. HMI 231 may be implemented on a tablet, laptop, desktop computer, mobile device, kiosk, or similar. HMI 231 may be representative of HMI 140, HMI 213, HMI 224, or other HMI versions for machine learning assets as discussed herein. HMI 231 is displaying faceplate 232, wherein faceplate 232 provides information relevant to the machine learning asset to which HMI 231 is communicatively coupled. Faceplate 232 provides information relevant to the status of the machine learning asset as well as basic options for controlling or adjusting the machine learning asset from within the field environment. In an example, an operator may view faceplate 232 for information about the current status of the machine learning asset or may use controls provided on faceplate 232 for adjusting and/or controlling the machine learning asset.

FIG. 3 illustrates an industrial automation environment in which one or more machine learning assets may be utilized to predict or control an industrial process based on live HMI snapshots and/or captured images of the industrial process itself. FIG. 3 includes industrial automation environment 300, wherein industrial automation environment 300 comprises operator 305, HMI 310 comprising display 311, camera 315, and industrial line 320.

In certain environments and circumstances, there is additional information or subtleties that can be captured through visual inspection of an HMI (e.g., display 311) and the actual production environment (e.g., images of industrial line 320 from camera 315). In the past, operators have used their own inspection and knowledge to assist manufacturing processes in ways that are not or cannot typically be derived through data analysis. Thus, machine learning assets can be used for visual inspection of HMIs and/or the line itself (e.g., machinery, devices, etc.). Images are provided as input to a convolutional neural network or similar for making predictions or decisions that can then be used to inform control logic. In accordance with the present disclosure, snapshots may be taken of an HMI and/or the line itself and then correlated with a data pipeline via screen scraping and/or image recognition.

To train a machine learning asset in accordance with the present example, HMI images may be leveraged that indicate overall process state at different points in time or historical commands or similar HMI data can be correlated with the data pipeline. Historical examples may be used to train the model so that the model is able to find correlations. The layout of an HMI can be utilized to automatically develop and train models that react or predict based on the state of HMI images. In some examples, an entire image may be leveraged for training or feeding the machine learning asset while in other examples just specific sub-sections of an image may be utilized. In this way, subtler information that may not be present or extractable in the process data can be discovered and utilized without the need for thorough visual inspection by an operator, data scientist, or similar user. A trained machine learning asset consumes samples of images over time and provides output such as detecting or predicting a dangerous environment before the data would normally trip or trigger a warning.

Currently, an operator may observe an HMI, think about it, and make a decision about what steps to take based on the visual indicators present in the HMI. However, by capturing manual inputs on visual screens shown over time, a machine learning asset can find corollaries based on past interactions, displayed data, and inputs into the control system. From this data, a model can be trained to make decisions without the need for additional operator input and/or inspection.

Moreover, images of an industrial process captured via camera can play similarly useful roles. There are certain things, such as specific types of quality issues, that cannot be represented in data because there is not the right instrumentation to do so, but they can be visually observed, typically by an operator. For example, there may be no sensor that captures the amount of debris on a roller, even though you may be able to get the resulting behavior from data. Thus, a camera may be used to collect images (or a video camera to collect videos) at certain points on an industrial line. Collected images or videos can then be provided to a machine learning asset trained to identify particular issues. The machine learning asset may then output a determination that informs control logic based on a condition of the line.

Thus, in industrial automation environment 300 one or more images may be captured of display 311 on HMI 310, wherein the images include all or part of the data shown in display 311. The data shown on HMI 310 is relevant to one or more devices on industrial line 320. The images of display 311 may then be provided to one or more machine learning models, which may include one or more of machine learning asset 139, machine learning asset 211, or machine learning asset 222 in some examples, in addition to other implementations of machine learning models. The one or more machine learning models are configured to then analyze the operating condition of the of one or more devices. Based on an output from the one or more machine learning models, an operating condition or status of the one or more devices can be identified, a prediction can be made, a decision can be made, or a similar action can be taken. In one example, HMI 310 may present a notification or alert to operator 305 based on the output. Alternatively, the output may be fed directly back into the process code such that immediate changes can be made.

Similarly, one or more images that are captured via camera 315 can be used as input to one or more machine learning models, wherein the images captured via camera 315 include a portion of industrial line 320. The one or more machine learning models are configured to then analyze an operating condition of one or more devices. Based on an output from the one or more machine learning models, an operating condition or status of the one or more devices can be identified, a prediction can be made, a decision can be made, or a similar action can be taken. In one example, HMI 310 may present a notification or alert to operator 305 based on the output. Alternatively, the output may be fed directly back into the process code such that immediate changes can be made.

FIG. 4 illustrates a process for using live images from an industrial automation environment to detect issues, make predictions, make decisions, and/or control an industrial process. Process 400 includes step 405 in which one or more images are collected and used as input into a machine learning model in step 410. The one or more images may comprise HMI snapshots, photos of the industrial process itself, or videos. In step 410, the images are provided as input to a convolutional neural network which is trained to analyze the images for one or more states indicative of an issue. The neural network then outputs its prediction in step 415, wherein the prediction comprises any output determined by the neural network in step 410 that may be indicative of a current status or future status of the industrial process. Finally, in step 420, an alert is produced or an action is taken based on the prediction. For example, an alert may be produced that can be displayed on the HMI or communicated to specific persons or devices. Alternatively, an action may be taken in response to the prediction, such as an adjustment of parameters, values, or settings or a more drastic measure such as shutting down the line, turning off an asset, or similar actions. Actions automatically taken in response to machine learning predictions may be largely applicable in autonomous industrial environments.

FIG. 5 illustrates an additional use for implementing machine learning assets into industrial control—asset optimization and multiple model orchestration. FIG. 5 comprises industrial control loop 500. Industrial control loop 500 includes optimization model 505, I/O 510, HMI 515, PLC 520, actuators 525, controlled process 530, and sensors 535. Industrial control loop 500 may be one embodiment of the industrial control loops illustrated in FIG. 2B or 2C. In industrial control loop 500, optimization model 505 is a machine learning model configured to optimize the operation of controlled process 530 according to a current model control scheme.

In accordance with the present disclosure, machine learning models may be used to optimize a specific asset or process according to a specific goal or model control scheme. For example, a first machine learning model may be built for optimizing the performance of an asset and may be used when an identified goal is to optimize the performance of said asset (i.e., the model control scheme optimizes performance). A second machine learning model may be built for optimizing the yield of the asset and may be used when the identified goal is to optimize the yield of the asset (i.e., the model control scheme optimizes yield). Thus, in accordance with the present disclosure, a pre-built set of models may be established for optimizing an industrial asset or industrial line, via the control code, according to what should be optimized at the time (i.e., performance, yield, energy consumption, etc.). When it is determined or indicated that something different should be optimized, the model, such as optimization model 505, may be swapped out for another model. Models may be swapped out manually or may be swapped out automatically in response to some external factor triggering the swap.

In some examples, models are pre-built for specific asset types and can be utilized by an industrial programmer or data scientist with little to no knowledge required as to how the model internally works. In some examples, plugging an optimization model into the control code may be all that is required of a programmer. In other examples, a programmer may be required to fine tune optimization models for their particular application.

An optimization model, in accordance with the present example, uses machine learning to inform or set parameters of control code in order to optimize for a specific goal. Over time, a model will learn how to optimally adjust parameters to meet the output goal based on various conditions that exist within a specific environment. A key aspect of the optimization technology described herein is that the model is working to fine-tune parameters and control code based on needs or goals—the model is not being fine-tuned to predict better, as may be performed by previous technologies.

In an example, optimization model 505 may be representative of a high-performance model wherein the process is optimized to produce as much product as possible. Then, for some external reason, it is determined that the process should now be optimized for yield rather than performance. Thus, optimization model 505 is automatically swapped for a high-yield model which then can be used to adjust control code to optimize yield and/or run a different model control scheme.

Determining which model to use and when to swap models may be based on external factors provided or learned via I/O 510. For example, it may be known that performance should be optimized, but only when energy costs are low. This logic may be built into control or overall model orchestration logic, wherein input is energy prices. Thus, if energy prices are high, optimization model 505 can be swapped with another model that is tuned for energy conservation, rather than having excessive costs or needing to shut down the line. In this example, the outputs from the model are the same as well as the way they are connected into the control code. However, the decisions the model makes will differ based on how the model is trained and what its tuned for.

In some examples, asset optimization and model orchestration may be performed in part based on external information—such as current energy prices in the previous example. However, in some examples, asset optimization and model orchestration may be performed in an entirely closed-loop environment without any live external data. Optimization and orchestration logic may make swapping decisions based on data changing within the loop, such as a degradation of controlled process 530, time of day, ambient air temperature, or any other factor that could similarly trigger a model swap.

FIG. 7 illustrates process 700 for implementing machine learning models into industrial automation environments. In step 705, a computing system displays a graphical representation of a machine learning asset in an industrial automation environment, wherein the graphical representation includes a visual indicator representative of an output from the machine learning asset. In some embodiments, the machine learning asset comprises a model that uses operational data from the industrial process as input. In other embodiments, the machine learning asset comprises a model that uses external data obtained via a network as input. The graphical representation may include an option (e.g., a button or toggle) to turn the machine learning asset off, wherein turning the machine learning asset off comprises disconnecting the asset from the industrial process. The graphical representation may further include a menu for adjusting or tuning the machine learning asset.

In step 710, the computing system adjusts the visual indicator based on the output from the machine learning asset. The visual indicator may comprise one or more of many different representations such as charts, graphs, lines, numerical values, and the like. Examples of visual indicators may include those shown in faceplate 232 of FIG. 2D and display 311 of FIG. 3 .

In step 715, the computing system controls an industrial process in the industrial automation environment based at least in part on the output from the machine learning asset. The industrial process, in accordance with the present example may include a plurality of industrial assets on an industrial line, or may include a single industrial asset or a portion of an industrial asset. In some embodiments, the computing system controls a second industrial process in the industrial automation environment based at least in part on the output from the machine learning asset. In an exemplary embodiment, operational data from the industrial process is provided back to the machine learning asset.

FIG. 8 illustrates process 800 for using HMI snapshots to identify operating conditions in an industrial automation environment. In step 805, a computing system captures one or more images of an HMI in an industrial automation environment, wherein the one or more images includes at least one visual depiction of data collected from an industrial device in the industrial automation environment. In step 810, the computing system provides the one or more images to a machine learning model configured to analyze an operating condition of the industrial device in the industrial automation environment, wherein the machine learning model, in some embodiments, is a convolutional neural network. In step 815, the computing system, based on an input of the machine learning model, identifies a current operating condition of the industrial device, wherein the current operating condition may be indicative of an issue related to the performance of the industrial device. In an exemplary embodiment, the computing system edits control logic for the industrial device based at least in part on the output of the machine learning model.

In addition to or instead of the HMI snapshots, the computing system may capture one or more images of the industrial device itself. The computing system may further provide the one or more images of the industrial device itself to a machine learning model configured to analyze an operating condition of the industrial device in the industrial automation environment, wherein the machine learning model may be the same machine learning model as in step 810 or may be a different machine learning model. Based on an output of the machine learning model, the computing system may identify a current operating condition of the industrial device. Process 800 may further include training the machine learning model to identify operating conditions of the industrial device based on historical images and/or training images.

FIG. 9 illustrates process 900 for optimizing parameters in an industrial automation environment. In step 905, a computing system maintains a set of model control schemes for controlling an industrial process in the industrial automation environment, wherein each model control scheme comprises at least one machine learning model configured to optimize one or more parameters. In step 910, the computing system controls the industrial process with a control program running a first model control scheme from the set of model control schemes, wherein the first model control scheme is configured to optimize a first parameter of the industrial process. In step 915, the computing system is configured to replace the first model control scheme with a second model control scheme, wherein the second model control scheme is configured to optimize a second parameters of the industrial process, wherein the industrial process comprises running one or more industrial devices controlled by the control program on an industrial line. In one example, replacing the first model control scheme with the second model control scheme occurs in response to a direction to swap the first model control scheme out for the second. In an alternative example, replacing the first model control scheme with the second model control scheme occurs automatically in response to an indication that the second parameter should be optimized. In some embodiments, the first parameter comprises at least one of performance, yield, and energy conservation.

FIG. 10 illustrates process 1000 for performing model lifecycle management (MLM) in an industrial automation environment. In step 1005, a computing system runs an industrial process, in the industrial automation environment, with a control program, wherein the control program comprises a first machine learning model and the first machine learning model uses, in part, real-time data from the industrial process as input and produces parameter values used in the control program as output. In step 1010, the computing system measures a gap between outcome data predicted by the first machine learning model and outcome data of the industrial process. In step 1015, the computing system determines, based on the gap, that the first machine learning model has degraded past a degradation threshold. In step 1020, the computing system replaces the first machine learning model in the control program with a second machine learning model, wherein the second machine learning model is trained based at least in part on the actual outcome data of the industrial process.

In some embodiments, the second machine learning model of process 1000 is a retrained version of the first machine learning model. In other embodiments, the second machine learning model may be a new model. In certain examples, the computing system, prior to determining that the first machine learning model has degraded past the degradation threshold, adjusts the first machine learning model based on real-time data from the industrial process. In an example, the machine learning models in process 1000 are predictive models. However, in performing the steps of process 1000, the computing system may be running a prescriptive model wherein the prescriptive model is responsible for closing the gap in the residual. The steps of process 1000 may similarly be performed to manage lifecycles of prescriptive models. The model running in process 1000 may require automatic retraining or replacement itself and such model management is anticipated by the present model lifecycle management system. Moreover, in many examples, the industrial automation environment of process 1000 is an autonomous manufacturing environment.

Thus, as described in process 1000, machine learning models may be implemented to perform model lifecycle management and process optimization. Model lifecycle management, in accordance with the present discussion may serve to replace or improve traditional asset management in industrial automation environments. In process 1000, machine learning is used to track and/or recognize gaps (i.e., errors or residuals) between predictive and actual outcomes. A model inherently has a useful lifecycle as the environment around it changes. Over time, models become ubiquitous and can, in essence, wear out, just like any other machine or sensor on an industrial line. Once degradation of a model starts, it is advantageous to retrain the model, change inputs or parameters of the model, or train a new model to replace it. To perform these prescriptive tasks, optimization models are used to solve for what and how to change the model—that is, which variables to change and how to change them, when and how to retrain the model, and when and how to replace the model. In this way, models can be scheduled for updates, maintenance, and even repair in a predictive and automated fashion. Lifecycle management models within an autonomous manufacturing plant may operate at different levels of control—models may optimize control variables, assets, lines, or even entire plant schedules.

In accordance with the present disclosure, machine learning may be utilized in lifecycle management of models that are focused on the closed-loop control of assets in production lines and manufacturing, as well as in the management of models that exist in open-loop settings. The models in an industrial automation environment may require consistent monitoring, evaluation, reparameterization, and retraining, and this process is ideally done in the context of the machines being controlled or the processes being optimized. MLM models may advantageously be responsible for evaluating the performance of each asset in a line in a plant at all levels and understanding how their performance relates to the performance of models that are autonomously driving those assets. From this information, an MLM model automatically determines what should be done to the models to upkeep them, retrain them, reevaluate them, and the like. In effect, the model lifecycle management component of the industrial automation environment becomes a discipline that is integrated into the overall process and management procedures, operating on both the predictive and the prescriptive side to manage all levels in an integrated fashion.

In order to retrain a model or train new models, the prediction error may be used as feedback into one or more models such that the error itself can be used to train the model. In an example, a first model is running and has a certain level of accuracy or certain error between the predicted and the actual data. A second model is then used which targets the reduction of the error itself. In some examples, a gradient-boosted tree may be used to perform this reduction of error task. The second model may be running at all times such that there is continuous effort to improve the first model's error with automated re-training or re-learning, or the second model may alternatively only run at prescribed times. However, in both instances, the models may be used simultaneously with operation—that is, there is no need to shut down the line and retrain a model as it falls out of tune.

In an example, the MLM system described herein is implemented in an autonomous tire manufacturing plant that has several core process areas and classes of assets required to run the plant effectively: mixing, extrusion, assembly, curing, and inspection. In a typical tire manufacturing scenario, a plant manager may be personally responsible for observing performance, consistency, and quality at each stage of production. Under this scenario, the performance of a plant may be primarily a consequence of how well-conditioned the physical assets are and how well the control logic is implemented into the PLCs for controlling the assets. However, using machine learning to implement the optimization process, the performance in each area becomes a consequence of how effective the MLM models are that are autonomously controlling the processes. For example, performance may be a measure of how effective the model is that controls a splicing operation, how effective the models are that control mixing, energy, time, and power curves to obtain optimal viscosity, or how effective the models are that control the temperature, pressure, and time dynamics of the vulcanization process.

In the example of the tire manufacturing plant, a model may be in use that controls the curing process, wherein the model predicts that a certain combination of temperature, energy, time, and pressure inputs will produce a certain vulcanization output. To assess the accuracy of that prediction, the gap between the predicted output and the actual output is measured to obtain the error or residual. This gap is monitored over time and the model may be continually adjusted or trained such that the gap actually shrinks over time rather than grows. Once an inflection point appears indicating degradation, the MLM system may determine that one or multiple actions are required including retraining the model with new data, adding a new variable or new parameters, changing a variable or parameter, implementing a different modeling configuration, or performing a form of maintenance on the model. Thus, the mathematical metric, or the error, is used to kick off the model maintenance process, wherein the MLM platform is used to organize and automate the process along the way.
